This one was the best..though I cannot find the whole story anymore...but it was funny as hell...here's what I could find.
Another Griffiths' stunt involving Mount Trashmore wasn't received so well. On April 1, 1992, Griffiths and then partner, Henry ``The Bull'' Del Toro, pulled off a modern classic April Fool's caper. Like the Orson Welles' 1939 Mars Invasion spoof, the radio duo used a mock news report, complete with phony seismic information from the University of Virginia and on-air calls from ``experts'' (who in reality were Griffiths' friends). Though they thought they were giving obvious clues by naming fictitious evacuation highways the jokesters convinced hundreds of gullible residents that the hill was about to explode from a gas buildup inside.In the days following the event, numerous radio employees were temporarily suspended from the airwaves without pay. It seems the FCC was not amused when local ``911'' lines were deluged with calls from concerned citizens.The disc jockeys and citizens were unaware that the methane gas the decaying matter inside the hills actually generates is harmlessly vented by three inconspicuous hollow flagpoles planted along the ridge of the hills
